LANDFILL GAS MONITORING <br /> GEM 500 CALIBRATION AND PERTINENT DATA <br /> Date: Site Name: <br /> Technician: Job No. <br /> WEATHER OBSERVATIONS <br /> Wind Speed: 1— MPH Wind Direction: g <br /> p �_ ��l Barometric Pressure/:•3�/'t° 'H <br /> Air Temperature: S�, °F General Weather Conditions: Vic / <br /> CALIBRATION INFORMATION <br /> Pre-monitoring Calibration Precision Check <br /> Procedure: Calibrate the instrument. Make a total of three measurements by alternating zero air <br /> and the calibration gas. Record the readings and calculate the average algebraic difference <br /> between the instrument reading and the calibration gas as a percentage. The calibration <br /> .precision must be less than or equal to 2% of the calibration gas value. - <br /> Instrument Serial No. &32.7 <br /> Calibration Gas: %CH4:5D.0 %CO2 �.,0 %02 X_,l <br /> Time CH4 CO2 T 02 <br /> 075 __-Z, z <br /> Post-monitoring Calibration Check <br /> Time I CH4 CO2 02 <br /> 17&Vj <br /> NOTES: <br /> Calibration Form GEM <br /> 12/12/03 9:08 AM <br />
